Summary: WINE Steam using 100% of CPU when its doing nothing
Product: Wine
Version: 0.9.51.
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: wine-misc
AssignedTo: wine-bugs at winehq.org
ReportedBy: vektuz at cox.net
This is a recent development. When I run STEAM, it starts normally albeit
slowly, and then eats 100% CPU (on this single core machine) for its entire
lifetime. No matter which tab is displayed. This is a relatively new
development, and occurs for me both on Compiz native, and VMWare virtualized
installtions of Ubuntu/WINE 0.9.51 w/ Gnome.
I remember this working fine a couple builds ago, round about 0.9.48-ish.
As for clues to why this happens, I spoke to Valve about this behavior, and it
was suggested that it was polling to refresh the window very rapidly. I can
reproduce the behavior on Windows by running Steam on a remote windows machine
and using VNC (for example) to view it. It polls the window causing rapid
redraw, and results in 100% CPU on the remote computer whenever the VNC window
is being displayed. I'm posting this merely to indicate this might be a clue
as to why it happens. Its pretty disruptive when it does, because even if you
run a game via steam, it hogs the CPU. You have to essentially 'nice' it down
to background priority before the game runs smoothly.
This doesn't seem to stop you from actually running games/software, so its not
a critical bug, I suppose, but I figured I'd better submit it here because it
happens, and its new, and it didn't happen before.
